END-LASTING MECHANISM.

Application filed December 19, 1918, Serial No. 267,504. Renewed October 20, 1922. Serial No. 595,845.

T 0 all whom it may concern:

Be it known that I, CHARLES F.v PYM, a subject of the King of England, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain Improvements in End-Lasting Mechanisms, of which the following description, in ,connec tion with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in .the several figures.

This invention relates to ,machines for working uppers over lasts, and more par ticularly to mechanism forlasting the end portion of a shoe. The invention is herein shown as embodied in end lasting mecha nism particularly designed for use in a machine for pulling over a shoe and for lasting the toe portion of the shoe; but it will be understood that the invention, in its broader aspects, is not restricted in utility to machines for performing both pulling-over and lasting operations nor to machines in which the lasting mechanism is specifically designed for toe lasting.

An important object, among others, of the present invention'is to provide in machines of the above mentioned class improved lasting mechanism of such construction as to insure more accurate conformity than here tofore to the varying contours of different shoes and to render the same mechanism capable of successful use upon a wide range of styles and sizes of shoes. With these and other ends in view, a feature of the invention consists in a novel construction and arrangement of end lasting mechanism in which a plurality of over-working members are arranged to operate at the same side of the longitudinal median line of a shoe and are relatively movable into conforming relation to the contour of the shoe, together with operating means for rendering each member effective to Work firmly into lasted position that portion of the upper upon which it operates. The construction herein shown comprises end embracing wipers the opposite halves of which are sectional, with operating mechanism connected to the different sections and so constructed as to impart closing movement overthe shoe to each section individually, with provision for relative movement. of diiferent portions of the operating mechanism through compeneating connections in such manner as to ac- ,elerate the movement of one section when the movement of another section is retarded or stopped by reason, for example, of the resistance of the shoe materials. By the use of such mechanism the margin of the upper will be wiped in closely against the shoulder or rib of the sole or insole along the entire length of the portion of the margin under treatment without danger of wiping too far inward or of applying undue pressure at any portion of the shoe with consequent danger of breaking down the rib or of otherwise damaging the sole or insole.

The construction herein shown includes means for applying a binder to theshoe to hold the upper in lasted position and for forcing the ends of the binder into the shoe materials to anchor the binder in place, the illustrative construction thus involving features of theinvention disclosed in Letters Patent No. 1,436,194 granted upon my application on Nov. 21, 1922; and in a further aspect the present invention involves featuresof novelty in the binder applying means, some of which are related to wiping mechanism of the novel construction above described, while other features are independent of the particular construction of the means employed for working the upper into lasted position.

The above and other features of the invention, including also a novel organization for substantially equalizing the pressures of different wiper members on a shoe and certain' details of construction and combinations ofparts, will now be more particularly described with reference to the accompanying drawings and pointed out in the claims.

In the drawings:

Fig. 5 is a sec ion 0. .1 heli e 5-. of Fig. 1.-

The invention is herein shownfor purposes of illustration as embodied in mechanism designed for use in a machine of the type shown in the patent hereinbefore reterred to, comprising a front arm 2 shown in section in Fig. 1- and fragmentarily in side elevation in Fig. 2, this'arm being mounted for. operative swinging. movement lengthwise of shoe positioned for toe lasting, as fully explained in said patent. Mounted on the arm 2 is a wipersupporting block 4 suitably recessed to provide a guideway for a pair of wiper supporting gear segments 6 upon which the wipers are adjustably secured. The wipers, in accord ance with the illustrative embodiment of this invention, comprise a pair of end plates 8 connected by a pivot stud 10- arranged to be located substantially midway between the opposite sides. of. the shoe upon which the wipers are to operate and coinciding with the axes of thegear segments 6, the plates 8 thus being mounted, for relative closing movements over the margin of the sole or insole at the endof the shoe. Mounted on pivots 12 on the wiper plates Sat opposite sides of the center pivot 10 are additional wiper, plates 14 which are ar ranged to serve in effect as continuations ofv the end plates and to operate upon portions of the margin of the upper extending beyond the ends of the plates 8 along the opposite sides of the toe-portion of the shoe. llhe inner or wiping edges of the dilierent wiper sections 8 and 14 are curved in substantialconformity to the curve of. the edge of the shoe bottom, or the corresponding curve of the shoulder or rib ot' the sole or insole, the provision for relative movement of each plate 8. and the connected plate, 14 about the pivot12 permitting a variation in the relation between these plates contormable to the varying edge contours of shoes of different shapes and sizes.

For imparting operative closing, move ment to the wipers, the wiper support 4 carries pinions 16 arranged respectively to engage the teeth of the opposite gear seg ments 6,.and pinions 18 operatively connected to slidingrack. bars 20 which are connected at. their inner ends by means of links 22 to the side or. extension wiper plates or sections 14. For imparting operative movement to the pinions 16 and 18 the support 4 carries sliding rack bars 24 and 26 arranged respectively in operative engagement with said different pinions, the outer ends of each pair ,of rack bars 24 and 26 being connected together by means of a transverse cross-bar or link 28, the connections between this link and the rack bars being so constructed as to afford sufficient play to provide for relative lengthwise movement of the different rack barsl Pivotally connected to each link 28 betweenthe opposite ends of the link is an operating rod 30, these rods in the present construction being supported and guided in the lower ends of members 32 which may be pivotally mounted on the machine substantially as described in the patent above referred to, to serve as means to render the wiper clos ing mechanism operative at a definite point in the bodily movement of the wipers toward the shoe. Mounted on the rods are springs 34 bearing at their inner ends on the members 32 and at their outer ends on adjustable nuts 36 on the rods, the springs 34 thus tending to hold the members 32 in engagement with stop shoulders 38 on the inner end portions of the rods. It will be understood that, as explained in said patent, the movement of the arm 2'and its supported wiper mechanism toward the shoe carries the members 32 into engagement with stops independently adjustable with respect to each member to determine the time when closing movement of the respective opposite side portions of the wipers shall begin. Springs 40 connected to the members 32 and to pins. 42 on the support 4 are arranged to assist in the return of the parts to starting position in substantially the, same manner as in the construction of my prior patent.

In the operationof the construction as thus far described, the members 32, when their movement toward the shoe is stopped as above explained, are rendered operative through the springs 34 to stop lengthwise movement toward the shoe of the rods 30 and the connected rack bars 24 and 26. As the support 4 continues its movement toward the shoe these bars are thus rendered effective to impart turning movement to the pinions 16 and 18 mama direction as to operate the gear segments 6 and the rack bars 20 respectively for swinging the dilierent wiper sections simultaneously about their pivots 10 and 12 to close them round the end of the shoe and to Wipe the margin of the upper inward over theft-rather oi the sole or insole. If one or the other of the sections 8 or 14 at either side of the shoe din-in g this movement encounters greater resistance than its con nected sections its movement may in consequence be retarded or stopped teniporarily and the movement of the connected section will be accelerated by reason of the compensating or. equalizing connection. 28 between theraelt bars 24 and 26, and as soon as the resistances are again substantially equalized, the vdifi'erint wiper sections will continue their inward closing movements together at normal relative rates of speed. Similarly, by reason of the equalizing connection bet'ween the raclr bars, if either of the respective wiper sections arrives earlier than the other in position toforce the margin of the upper "firmly against the shoulder or rib oi ill) Cal

the sole or insole, its inward closing movement will be substantially stopped and the movement of the other wiper section will be accelerated until it also arrives substantially at the proper limit of its overwiping n'iovement during the continued movement of the wiper mechanism as a whole lengthwise of the shoe, thereby substantially equalizing the pressures of the different wiper members on the shoe. In case both wiper sections 8 and 14 at one side of the mechanism complete their overwiping move ment laterally of the shoe earlier than the sections on the opposite side, the construction further affords provision for yield of one or the other of the springs 34 to permit the Wiping over operation at the opposite side of the shoe to be completed, in a manner similar to the construction of my prior patent.

As hereinbefore stated, the construction shown includes means for applying a binder to the shoe for holding the upper in lasted position and for forcing projecting portions, such as inturned, ends, of the binder into the shoe materials to anchor the binder in place. For this purpose, in the present construction, each of the wiper sections 14 is provided with a driver plate 44 pivoted on the same stud 12 as the wiper section, said plate, which is of substantially the same thickness as the binder, having its lower surface substantially flush with the lower over-wiping surface of the end wiper sections 8, as shown in Fig. 3. The plate 44, as thus mounted, is positioned between the Wiper section 14 and a plate 46 which is secured at its ends to the section 14 and is recessed on its upper side between its ends to provide a space in which the driver plate may swing freely. Springs 48 connected to the plates 44 and to the supporting block 4 are arranged to hold the driver plates normally in retracted position as shown in Fig. 1. vVhen the plates are thus retracted a space is provided in front of the inner edge of each plate 44 and between the section 14 and the underlying plate 46 to receive the end portion of a wire binder a, thus premitting the plates 46 to support the ends of the binder in position to be applied to the shoe. As the binder is thus supported, its intermediate portion extends in front of the inner edges of the end wiper plates 8 which, as above explained and as shown in Fig. 3, extend downward farther than the plates 14 a distance substantially equal to the thickness of the driver plates 44 and of the binder. In order to assist in supporting this intermediate portion of the binder, the wiper sections 8 are each provided with a plunger 50 normally held by a spring 52 with its end projecting beyond the front edge of the plate 8 in position to support the binder when the lattervis inserted in the wiper mechanism. As thus positioned the plungers 50 are arranged to engage the end face of the shoe in the operative forward movement of the wipers, the springs 52 then yielding to permit the wipers to close over the shoe. It will be evident that in the operation of this construction the intermediate portion of the binder is forced inwardly over the feather of the sole or insole ahead of the wiper plates 8 and by the action of theseplates, portions of the binder which are indicated in dotted lines in Fig. 1 as located back of the front edges of the side wiper plates 14 remaining in substantially the same relation to the edges of these plates under the control of the driver plates 44 which are moved inwardly with the plates 14 in the operation of the latter, until the overwiping operation has been substantially completed.

In the construction shown the end wiper plates 8 are undercut, as indicated in Fig. 4and by dotted lines in Fig. 1, to provide abutment faces 54 curved in substantially parallel relation to the front edges of the plates and spaced backwardly from the edges a distance substantially equal to the width of the feather of the sole or insole, the plungers 50 being mounted in these undercut portions. In operation the abutment faces 54 are thus carried into engagement with the end face of the shoe when the wipers have substantially completed their over-wiping movement, and such faces may serve by engagement with the shoe to limit the operative movement of these wiper plates and the movement of the wiper mechanism lengthwise of the shoe, as well as to assist in forming the upper along the edge of the shoe bottom. A similar function is performed for the wiper sections 14 by the plates 46, the front faces of which are curved similarly to the front edges of these plates and are arranged to engage the lateral periphery of the shoe similarly to the abutment faces 54 on the end plates. Tie construction thus afl'ord provision for relative movement between the parts which engage the lateral periphery of the shoe as well as, and in substantially the same manner as, the different wiper sections, insur ing thereby that the lateral periphery of the shoe shall be closely embraced along the length of the portion of the shoe upon which the wiper mechanism is operative to assist "in shaping the shoe as well as to guide the binder into its proper relation to the shoe and to limit the movement of the wipers.

For operating the driver plates 44 the machine is provided with driver members 56 pivotally mounted on the wiper support in position to engage the plates and force them inward against the tension of the springs 48, these members being operated ill) through gearing 58 from crank arms 60 in a manner substantially as explained in my prior patent. This mechanism is operated when the overwiping movement of the wiper v plates has been substantially completed, to

force the binder closely into the angle between the feather and therib of the sole or insole along the opposite sides of the shoe and to force the inturned ends of the binder into the shoe materials in directions substantially parallel to the plane of the shoe bottom to anchor the binder in place. It will be understood that the plates 44: in their inward movement have also a supplemental overwiping action on the shoe upper in the same plane as the lower faces of the end plates 8.

In mechanism of the class described, end embracing wipers comprising wiper sections arranged to extend in a series round the end of a shoe with a plurality of sections ateach side of the longitudinal median line of the shoe, the different sections at each side being mounted for relative swinging movements laterally of the shoe, a support "for said wipers movable to carry them lengthwise of the shoe, and operating means for closing the Wipers inward laterally of the shoe including a member at each side of the mechanism relatively to which said wiper support is movable, and connections between said members and the different respective wiper sections at the corresponding sides of the mechanism including compensating devices to permit relative move ment of the different wiper sections at each side in response to differences in resistance encountered in the overwiping operation.

41. In mechanism of the class described,

end embracing wipers comprising a phi-- rality of wiper sections arranged to extend in a series round the end of a shoe with a plurality of sections at each side of the longitudinal median line of the shoe, the different sections at each side being relatively movable laterally of the shoe in the overwiping operation, a wiper support movable to carry said wipers lengthwise of the shoe, a plurality of pinions on said support connected to the different wiper sections, rack bars engaging the different respective pinions, a cross-link between the rack bars at each side of the mechanism, operating rods connected respectively to the different links, and means yieldingly con-- nected to said rods to render the rods operative through movement of the wiper support to impart lateral swinging movements to the different wiper sections.

42. In mechanism of the class described, end embracing wipers comprising a plurality of relatively movable wiper members, a wiper support movable to carry said members lengthwise of a shoe, operating members connected respectively to the different wiper members, an equalizer between said operating members permitting them to move relatively in response to differences in resistance encountered by the different Wiper members, and means acting through said equalizer to render said operating members effective to close the wiper members inwardly over the shoe in response to movement of the wiper support lengthwise of the shoe.

43. In mechanism of the class described.

end embracing wipers comprising a pluralbers lengthwise of a shoe. and operating means for imparting to said wiper members closing movements inwardly over the shoe in response to movement of said support lengthwise of the shoe comprising an equalizing connection between said different members responsive to differences in resistance encountered by said members substantially to equalize the pressures of the different members upon the shoe.

44. In mechanism of the class described, end embracing Wipers comprising a plurality of relatively movable Wiper members, pinions connected to said wiper members to close them inwardly over a shoe, rack bars connected respectively to the different pinions to operate them, and controlling means for said rack bars comprising an equalizing connection between said bars operative in response to differences in resistance encountered by the different Wiper members substantially to equalize the pressures of said members upon the shoe.

In testimony whereof I have signed my name to this specification.
